IMPROVEMENT |N TEMPORARY BINDERS.

Specification forming part of Letters Patent N 0. 195,226., datedSeptember 18,1877; application filed August 27, 1877.

To all whom it may concern:

Be it known that I, JOHN W. MUNDAY, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvements inLetter-Files, of which the following is a specification In theaccompanying drawings, which form a part of this specification, Figure 1is an end view of the file closed. Fig. 2 is a similar view of the same,showing it partially open, as when a letter is to be inserted orremoved. Fig. 3 is a flat view of the folio; and Fig. 4 is a fiat viewof one of the index-sheets removed from the folio.

Like letters of reference denote like parts 'in the several figures.

In the said drawings, A represents a portfolio made of stiflishmaterial, and provided with a flexible back, B. The lids of the folioare attached together at each end by an elastic guard, O, which servesthe triple purpose of preventing the contents of the portfolio fromslipping out at the ends, holding the lids closed when the file is laidaside, and of preventing the lids from being separated too far apartinopening the file.

Within the portfolio are placed a series of loose index-sheets, D, asshown at Fig. 2. This completes the file.

In use, the letters E E to be filed are simply slipped loose into placebetween the indexleaves, and when the file is full the whole may bestored away.

I claim The letter-file consisting of a portfolio having stiff lids anda flexible back, in combination with the loose index-sheets and theelastic guards attached to the ends of the lids at both ends,substantially as specified.

JOHN W. MUN DAY.
